The Plus plan, which is targeted towards small project groups, is available for $49 per month and supports an unlimited number of users. It also offers 15 GB of storage and accommodates up to 35 projects. For large groups, the Premium plan offers 30 GB of storage, unlimited users, and support for up to 100 projects at a price tag of $99 per month. The most expensive plan, called Max, provides unlimited projects and users with 75 GB of storage at a cost of $149 per month. There is also a free plan which allows for an unlimited number of users, a single project, but no file sharing. All paid plans include the full suite of features and the ability to purchase add-ons, such as mobile device support and integration with third party software.
According to proponents, monitoring is, in some ways, the greatest advantage of the Critical Chain method. Because individual tasks vary in duration from the 50% estimate, there is no point in trying to force every task to complete "on time;" estimates can never be perfect. Instead, we monitor the buffers created during the planning stage. A fever chart or similar graph can be created and posted to show the consumption of buffer as a function of project completion. If the rate of buffer consumption is low, the project is on target. If the rate of consumption is such that there is likely to be little or no buffer at the end of the project, then corrective actions or recovery plans must be developed to recover the loss. When the buffer consumption rate exceeds some critical value (roughly: the rate where all of the buffer may be expected to be consumed before the end of the project, resulting in late completion), then those alternative plans need to be implemented.
